Development build with preact watch --src src/docs works and using --no-prerender gives this output:

What is the expected behaviour?

If this is a feature request, what is motivation or use case for changing the behaviour?

Please mention other relevant information.

Please paste the results of preact info here. ← does not work

preact-cli 2.2.1
...
Unbekanntes Argument: info

[prateekbh]

The reason is that the prerendering work in node environment and does not wait for async operations to be over.

If you want you can wrap it in an if condition and make sure that it is not reachable in prerendering flow

[ForsakenHarmony]

The progress indicator showing up twice is probably conflicting logging preventing it from getting cleared
